摘要：

The cell adhesion molecules NCAM and L1 are considered to play key roles in neuronal development and plasticity. L1 has been shown to interact with NCAM, possibly through NCAM binding to oligomannosidic glycans present in L1, We investigated the effect of recombinant immunoglobulin (Ig) modules of NCA-IM involved in homophilic NCAM binding, on L1 induced neurite outgrowth from PC12-E2 cells and found a complete inhibition of L1 induced neurite outgrowth after addition of Ig-modules 1, 2 and 3 of NCAM, suggesting that the ligation state of NCAM is crucial for normal L1 signaling.
